Financial Planning in Nigeria: A Guide for Internationally Mobile Investors

Nigeria is Africa's most populous nation, with over 220 million people, and its largest economy by GDP. Lagos — Nigeria's commercial capital — is one of Africa's most dynamic and fastest-growing megacities, a centre of finance, technology, entertainment, and enterprise. Abuja, the federal capital, is a planned city that has grown rapidly into a significant commercial hub in its own right.

For high-net-worth individuals with Nigerian connections — whether resident in Nigeria, part of the large and prosperous Nigerian diaspora in the UK, the US, and the UAE, or international investors with exposure to the Nigerian market — financial planning presents a distinctive set of challenges and opportunities. This guide covers the key considerations.

The Nigerian HNW Landscape

Nigeria generates significant private wealth, concentrated in the oil and gas sector, banking and financial services, real estate, telecommunications, and increasingly technology and consumer goods. The Nigerian Stock Exchange — now the NGX Group (Nigerian Exchange Group) — lists over 150 equities and a growing range of exchange-traded products.

Nigeria's wealthiest individuals and families typically maintain substantial international assets alongside their Nigerian holdings, reflecting the well-established practice of diversifying away from naira-denominated exposure. For the diaspora HNW community — estimated to number in the hundreds of thousands in the UK alone — cross-border planning is a constant feature of financial life: UK assets to manage, Nigerian family and property obligations to meet, and remittances to arrange.

Tax Residence and Personal Income Tax

Nigerian personal income tax is administered under the Personal Income Tax Act (PITA). The Federal Inland Revenue Service (FIRS) administers corporate and federal taxes; State Boards of Internal Revenue (SBIRs) administer personal income tax for individuals resident in each state.

Tax residency: An individual is resident in Nigeria for a tax year if present in Nigeria for 183 days or more in any 12-month period that coincides with the relevant tax year. Individuals domiciled in Nigeria (ordinarily resident) are also treated as tax resident regardless of the 183-day test in some circumstances.

Nigerian tax residents are taxed on their worldwide income under PITA. Non-residents are taxed only on Nigerian-source income.

Progressive income tax rates (PAYE — Pay As You Earn, for employees):

• 7% on the first NGN 300,000 per year
• 11% on the next NGN 300,000
• 15% on the next NGN 500,000
• 19% on the next NGN 500,000
• 21% on the next NGN 1,600,000
• 24% on income above NGN 3,200,000 per year

These thresholds, expressed in naira, become increasingly modest in USD terms as the naira depreciates. The practical top rate of 24% applies to relatively low absolute income levels by international HNW standards — meaning that high-earning Nigerian residents reach the top bracket quickly. A consolidated relief allowance (the higher of NGN 200,000 or 1% of gross income, plus 20% of gross income) provides some offset.

Capital gains tax: Nigeria levies CGT at a flat rate of 10% on chargeable gains from the disposal of assets (including shares and property). Gains from the sale of Nigerian government securities and Unit Trust investments are exempt. CGT is self-assessed and paid directly to the relevant tax authority.

The FX Challenge: Naira Volatility

The Nigerian naira (NGN) has been one of the world's most volatile currencies over the past decade, reflecting underlying macroeconomic pressures: dependence on oil export revenues, persistent fiscal deficits, import dependence in manufactured goods, and periodic intervention by the Central Bank of Nigeria (CBN) to support the official exchange rate.

The 2023-2024 FX liberalisation was a landmark policy shift. The CBN, under the Tinubu administration that took office in May 2023, unified multiple exchange rate windows into a single rate and allowed a significant devaluation — with the naira moving from approximately NGN 460 per USD to over NGN 1,500 per USD by early 2024. While painful in the short term (inflationary, and reducing the purchasing power of naira-denominated savings), the unification was widely welcomed by international investors and businesses as a step towards a more transparent and market-determined FX regime.

For HNW individuals with Nigerian-denominated assets: The long-term trajectory of the naira remains uncertain. Building an international portfolio denominated in hard currencies — USD, GBP, EUR — is a structural imperative for Nigerians with wealth preservation objectives. The domestic asset base (real estate, business equity, Nigerian equity market holdings) should be balanced against offshore allocation.

Repatriation of investment returns: Accessing foreign currency to repatriate investment returns from Nigeria has historically been challenging during periods of FX scarcity. The CBN's Investors and Exporters (I&E) forex window was designed to provide a more transparent mechanism for investors, but access has been constrained during periods of low oil revenues. The FX liberalisation improves the structural position but does not eliminate repatriation risk entirely.

The Banking Sector

Nigeria's banking sector is reasonably well-capitalised by African standards, notwithstanding periodic recapitalisation exercises. The Central Bank of Nigeria periodically mandates increased minimum capital requirements for banks.

Major banks for HNW individuals include:

• Access Bank (one of the largest by assets, with an expanding pan-African footprint)
• Zenith Bank (strong corporate banking, significant wealth management offering)
• Guaranty Trust Bank (GTBank/GTCO) — well regarded for innovation and customer service
• First Bank of Nigeria — the oldest bank, with a broad national network
• United Bank for Africa (UBA) — pan-African with 20+ country operations
• Stanbic IBTC (Standard Bank Group affiliate, providing private banking and wealth management)

For internationally mobile HNW individuals and the Nigerian diaspora, Stanbic IBTC Private Banking, Zenith Private Banking, and the Nigerian operations of standard international banks (Standard Chartered, Citibank Nigeria) are the primary wealth management options.

The UK-Nigerian Diaspora: Cross-Border Planning

The UK has one of the largest concentrations of Nigerian diaspora in the world — with a population estimated at several hundred thousand, including a substantial professional and business community in London. Many UK-resident Nigerians are UK tax residents (and some are UK domiciled), with significant UK financial obligations alongside Nigerian family ties and assets.

Cross-border planning for the UK-Nigerian diaspora typically involves:

UK property: A significant proportion of the UK-Nigerian HNW diaspora owns UK property — both primary residences and investment properties. UK-situated residential property has been within the scope of UK inheritance tax regardless of ownership structure since April 2017 (including residential property held through offshore companies). From 6 April 2025 the former non-dom and remittance-basis regime was abolished and replaced by a residence-based system: a new 4-year Foreign Income and Gains regime for recent arrivers, and IHT exposure now determined by long-term UK residence (broadly, UK-resident in at least 10 of the previous 20 tax years) rather than domicile. These changes materially affect the UK-Nigerian community.

UK pension optimisation: UK residents working in the UK accumulate pension entitlements. Ensuring proper use of UK annual allowances, understanding the interaction of UK pension income with Nigerian tax obligations for returning residents, and planning the optimal point and method of pension drawdown are important planning areas.

Remittances: Nigeria receives among the highest remittance flows of any African country — formal diaspora remittance inflows were around USD 21 billion in 2024 and approached USD 23 billion in 2025. Many HNW UK-Nigerians support family in Nigeria, maintain Nigerian property, and fund children's education. Tax-efficient remittance planning — using the correct legal channels, understanding the gift and remittance rules in both jurisdictions, and avoiding inadvertent reporting triggers — is a practical planning need.

Nigerian assets from the UK: UK-resident Nigerians investing in Nigerian equities, fixed-income securities, or Nigerian real estate must understand the UK tax treatment of these assets (income reportable to HMRC, CGT on disposal for UK residents). The UK-Nigeria Double Taxation Agreement provides some relief, though its scope should be verified with current treaty text.

The UK-Nigeria Double Taxation Agreement

The UK and Nigeria have a Double Taxation Agreement. The treaty provides for reduced withholding rates on dividends, interest, and royalties between the two countries, and prevents strict double taxation of income. Verify the current treaty rates with a qualified cross-border adviser, as the applicable rates depend on the specific income type and the residence status of the recipient.

For UK residents with Nigerian-source income (dividends from Nigerian shares, rental income from Nigerian property, business income from a Nigerian operation), the treaty provides the primary framework for claiming relief from Nigerian withholding tax against UK income tax liabilities.

Investment Environment

The NGX Group (Nigerian Exchange Group) lists equities in financial services, consumer goods, oil and gas, industrial goods, and telecommunications. Access Bank, Zenith Bank, GTCO, MTN Nigeria, Dangote Cement, and Nestlé Nigeria are among the most liquid counters. Nigerian equities provide naira-denominated exposure — and therefore currency risk for foreign investors — but can generate attractive NGN returns during periods of economic growth.

Nigerian Government Bonds (FGN Bonds) and Treasury Bills (T-Bills) are available in the Nigerian debt market. These offer NGN-denominated returns, with NGN interest rates historically high to reflect the inflation premium.

Eurobond investments: The Federal Government of Nigeria has issued USD-denominated Eurobonds in international capital markets. These provide USD exposure to Nigeria without naira risk and are accessible through international brokerage platforms.

Key Risks and Considerations

Currency risk: The naira's history of devaluation makes large naira-denominated savings a risk for internationally oriented HNW individuals. Maintain appropriate USD/GBP/EUR allocation.

FX repatriation: Even with the 2023-2024 liberalisation, the ability to repatriate funds from Nigeria can be limited during oil price downturns. Do not count on immediate repatriation of Nigeria-based investment returns.

Business environment: Nigeria's business environment carries corruption risk, contract enforcement challenges, and bureaucratic complexity. Due diligence standards should be high for any Nigerian business investment.

Tax compliance: Nigerian personal income tax compliance has historically been variable. The FIRS has been increasing its focus on high earners and individuals with offshore income. Maintain full compliance with PITA obligations.

Security: Lagos and Abuja have generally safe areas for HNW residents, but kidnapping and crime risks require active security management in some areas and contexts. Take current security advice.
